Write a multiplication equation and a division equation that this diagram could represent.

vivado [14]

Answer:

$3 * 18= 54$ and $54/18 = 3$

Step-by-step explanation:

Given

$Sections = 3$

$Measurement=18$ per section

$Total\ Measurement=54$

Required

Model the scenario

The model of this scenario is:

$Sections * Measurement = Total\ Measurements$

This gives:

<em /> $3 * 18 = 54$ <em> -- This represents the multiplication model</em>

Divide both sides by 18

$3 * 18/18 = 54/18$

$3 * 1 = 54/18$

$3 = 54/18$

Reorder

<em /> $54/18 = 3$ <em> -- This represents the division model</em>
